Today, I received a short message saying that I won the lottery in Happy Camp. Do you think this is true?

It must be fake. A website in www.hnwbbe.com calling itself "Where is Dad?" even sent me a multimedia message, but it was definitely a fake. Press it and ignore it. As people have said, there is only one official website. If you really win the lottery, how can you only use information as a means of verification?

Ignore it or call the police.
